Now that I downloaded Steam, I can't play Half-Life or CS training or anything anymore. :-( It just tries to start a new online game. I tried turning Steam off or turning off my Internet connection, what do I do?

Go to the Half life logo on your desktop, right click and go to properties. In there go to the valve folder and find the bright orange half life icon (By that i just mean it's brighter than the one on your desktop) it should say 'hl' underneath it. Click that and you will just be taken to the original Half Life main menu

Ummmm your instructions are flawed. No offence. but I went into the program files too and the same dag gone thing happened. but I did figure out how to play a single player game, the downside is that when I downloaded Steam and updated HalfLife, the save files got deleted so I'm back at the first part of the game. But I'm progressing MUCH MUCH faster this time around. As for CS traing, I'm screwed.
